Matlab function called from MS Word VBA

I have a MS Word function that needs to run a MATLAB function from a vba script. I am having the .m file stored in a location on computer and need to set the path in matlab to see this file. I am currently using a method of retrieving the full path name from the user so that I can use this file path to set the path in MATLAB. The fullpath name is stored in a variable called SelFile. This is the part of the code that I am struggling with. I would also like to pass parameters from vba to word. This parameter would be called temp. Is there a way to do this?

    Set Matlab = CreateObject("MatLab.Desktop.Application")
    Call Matlab.Execute(SelFile)
    Call Matlab.Execute("My_m_file", Temp)

Thank you,
